  • The whole life-cycle cost components of urban rail transit were studied, every indicator of subway cost and its proportion were analyzed quantitatively, subway earthwork cost and mechanical and electrical equipments cost were calculated in details. According to whole life-cycle cost analysis theory, the mathematical model of whole life-cycle cost for urban rail transit was built, its analytical steps were proposed, and subway ventilation and air conditioning system was put forward as an example. Analysis result shows that the earthwork cost is the largest among eight costs, accounting for 36.36%, with an average cost of 197 million yuan·km-1; the second is mechanical and electrical equipments cost, accounting for 19.83%, with an average cost of 107 million yuan·km-1. The cost of ventilation and air conditioning system is 41.804 million yuan, and the cost of platform screen door system is 32.378 million yuan, the cost of platform screen door system is lower, so the plan with higher capital cost may lead to the less operation cost, and the whole life-cycle cost of urban transport system may reduce.
